Powder Brown Tang

The Powder Brown Tang, also known as the Powder Brown Surgeonfish, Japan Surgeonfish, and White-faced Surgeonfish, has a brown body with a white mark on the cheek between the mouth and eyes. The pectoral, anal, and dorsal fins are dark brown with light blue highlights at the tip. The dorsal fin also has an orange stripe present. The tail is blue with a yellow vertical bar. Yellow striping runs along the body, against the anal and dorsal fins, forming a wishbone-shaped marking.

A 125 gallon or larger aquarium is necessary to provide plenty of swimming room. It is a very passive fish that will have trouble with other aggressive tangs. Keep only one per tank.

Although Tangs will eat meaty foods along with the other fish in the aquarium, it is important that they are offered plenty of marine based seaweed and algae. This will strengthen their immune system, reduce aggression and improve their overall health. Offer dried seaweed tied to a rock or use a veggie clip, and feed at least 3 times per week. Sea Veggies, Seaweed Salad and Ocean Nutrition are all ideal products and are very easy to use.

  1. I have a medium specimen in my reef tank and he is definitely the showcase fish in the tank – beautiful markings. The iridescent blue outlines on the dorsal and caudal fins look terrific under actinic lighting. A. japonicus is very hardy and lives in captivity fairly well.

  2. The Powder Brown Tang truly is an elegant selection; very passive and probably the more beautiful species amongst tangs. I have this fish in a reef tank with soft corals and polyps and it has never bothered any of my corals. This fish also has a very healthy appetite and will eat small pellet foods, brine shrimp and spirulina flakes without hassle. I would definitely recommend this fish to anyone who is looking for a beautiful, tropical ocean addition to the landscape of their aquarium. The soft blues, yellow, gray and light brown colors of this fish compliment the colors of the corals in my tank.
